Extract from Wikipedia article: Urnula craterium is a species of cup fungus in the family Sarcosomataceae. Appearing in early spring, its distinctive goblet-shaped and dark-colored fruit bodies have earned it the common names crater cup, devil's urn and the gray urn. The asexual (imperfect), or conidial stage of U. craterium is a plant pathogen known as Conoplea globosa, which causes a canker disease of oak and several other hardwood tree species.
Urnula craterium is a species of fungus in the family Sarcosomataceae. In St. Petersburg, Leningrad Oblast, and north-western Russia, it typically grows on decaying wood, especially birch and aspen, in moist, shaded areas. Fruit bodies are cup-shaped, 2-5 cm in diameter, with a dark brown to black exterior and a pale interior. They usually appear in spring and early summer. The fungus is relatively rare in the region, but can be found in forests and wooded areas with rich soil and abundant organic matter.

Russia, May 3, 2021Primorskoye Hwy, Sankt-Peterburg, Russia, 197755Observations of the fungus Urnula craterium in Leningrad Oblast and north-western Russia reveal its presence in recently cut dense bushes of willow under power lines. Specifically, between Lisiy Nos and Morskaya, west of Saint Petersburg, the Devil's Urn mushroom was found growing alongside Sarcoscypha austriaca on May 3, 2021. Close-up observations show the fungus's distinct shape, while side views reveal its stem growing on a stick in the cut willow bushes. The habitat suggests that Urnula craterium thrives in disturbed areas with abundant woody debris, such as under power lines where vegetation is regularly cut. These findings provide insight into the ecological preferences of this fungus species in north-western Russia.
